ED030631 - Lincoln Electric SuperArc L-56 ER70S-6 MIG Wire - 2 lb Spool

The Industry Standard for Quality Welding Wire

When it comes to MIG welding mild steel, few products have earned the trust of welders like Lincoln Electric's SuperArc® L-56®. This 2 lb spool is the perfect companion for your portable MIG welder, offering the same industrial-grade performance found in Lincoln's larger drums but in a size that fits your garage or shop equipment. If you are tired of fighting with poor-quality wire that sputters, tangles, or produces porous welds, switching to L-56® can significantly improve your welding experience. It is designed to be forgiving, helping you lay down smooth, professional-looking beads even if the metal isn't perfectly clean.

The secret to the L-56®'s performance is its high deoxidizer content. In the real world, you don't always have time to grind every piece of steel to bright metal. This wire contains added manganese and silicon that act as cleaning agents in the molten weld pool, floating impurities to the surface and preventing gas pockets (porosity) from forming. This makes it the go-to choice for automotive repairs, farm equipment maintenance, and general DIY projects where rust and mill scale are common realities.

Feedability is another area where Lincoln Electric excels. The copper coating on SuperArc® wires is applied with precision to ensure excellent electrical conductivity and smooth sliding through your torch liner. Poorly coated wires can flake, clogging your liner and causing erratic wire feeding that ruins your rhythm. Lincoln's MicroGuard® technology prevents this, ensuring a steady wire speed and a crisp, consistent arc. Whether you are running straight CO2 for deep penetration or a 75/25 Argon mix for a cleaner finish, this wire adapts to your setup to deliver reliable results every time you pull the trigger.

Why Choose Lincoln SuperArc L-56?

• Versatile Shielding Gas: Works great with both CO2 and Argon blends.
• Consistent Quality: Manufactured to strict tolerances for diameter and chemistry.
• Perfect Size: 2 lb spool fits most small 110V and 220V MIG welders.
